Teaching MPPSC Assistant Professor Mock Test Series 2025 Physics Electromagnetic Oscillations and Alternating Current AC Voltage Applied to a Series LCR Circuit
A sinusoidal voltage, of Erms = 200 V and frequency 50 Hz, is applied to a series LCR circuit which contains a resistor with R = 3 Ω, an inductor with XL = 8 Ω, and a capacitor with XC = 4 Ω. The average rate, at which energy is dissipated in the resistor, is
1
240 W
2
480 W
3
2400 W
4
4800 W
